Does it care about hz?Our cabin has a 230V load with the ClimateMaster Trilogy 45 Q-Series 2-ton heat pump.

Ah, I would have thought my Victron dealer would have brought this up. I don't understand the Hz differences but thanks for bringing that to my attention.What I mean is it generates simple 230VAC@50hz and we want 120/230VAC@60hz split phase for distribution and consumption.
Victron makes inverters that support 120/240VAC@60hz for the North American market.
I very glad I asked, this will remove a lot of jiggery-pokery from the system even if we go with transformers.
We really should have started here.
Do you have a power budget for each of the buildings?
By that I mean peak instantaneous power in kilo-watts and kilo-watt hours per day?
Can you make an itemized list of the 120 and 240 loads?
If you are in North America you probably have 240V 60 Hz?

Your equipment is presumably designed for the North American market which runs on 240 Volt 60 Hz. The European standard is 230 V 50 Hz.We're totally off grid. So we have whatever we build.
Got ya. Yeah, it's a dealer in North America selling it to us. I guess I should confirm with him though.Your equipment is presumably designed for the North American market which runs on 240 Volt 60 Hz. The European standard is 230 V 50 Hz.
It cares about brown bears. Outside of that, it hasn't gotten to the point of caring about hz. The interior walls aren't even done, we're still building it and powering stuff off a Goal Zero and a Honda generator.Does it care about hz?
So the Multiplus 2 model we're poised to buy can give out 8KW of power or so. If we bought another one and ran them together could we double the power we get to the cabin (so long as we plan for that with wire size)?

We are planning for that ClimateMaster GSHP and I'm not sure if it cares about hz or not. I'm going to hopefully talk to a dealer on Monday to get some of my electrical questions answered.
Why would that be the only things it would do for me? Wouldn't it also allow us to use more power?Yes, but it sounds like the only thing this would do for you is:
- Lighten your wallet: 1) second inverter, 2) even beefier wires to handle 2X the current.
- Increase your idle power consumption.

The GSHP alone can use up to 3KW/hr just for heating.You have yet to demonstrate a strong need for even 8000W. The 2500W you will have left over when the heat pump is running at max is enough for most folks. The heat pump will typically not run anywhere near that max power when it's just maintaining a temperature.
Since you're planning on doubling your power, are you also planning to double your array and double your battery?
Cool in that case you could run the auto-transformer local to the heat pump and isolate the complexity.It does. It explicitly states 60 on the already-linked info.
Additionally, every other 120VAC item you will buy will care too.
Again, MP II can be configured for 240VAC/60Hz.
I was just asking a question, I wasn't planning anything. I'm asking those questions in order to size wires to help me future proof.You have yet to demonstrate a strong need for even 8000W.

Your new plan is not clear to me.We're looking at the rainwater collection system we have yet to design and yet to build to try to figure out what power we'll need for water pump(s) to deliver water ten feet up to the cabin and the wife is looking at all the kitchen gadgets she's going to want in the future so we should have an idea of what kind of power we think we need before too long.
I'll deal with other structures later for power, I'm dropping them from this project and will deal with them later. This has gotten far too cosmic for me.
I think I will also move all the equipment to the cabin and just run a DC wire the distance. I've had enough of juggling ten things I know nothing about with a bankrupting price tag behind it.
I'm only concerned now with the PV location in the sunny spot, and our cabin 500 feet away. I don't want to deal with 12 wires for 14 split phases in 8 dimensions for 500 feet of trenching to the cabin.Your new plan is not clear to me.
Which structures are you dropping?
Where is the dc going at what voltage and amperage?
